  1. 1. Inductive fast charging of IoT devices : An in-depth analysis of short-range wireless charging technologies based on induction

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Franz Wikner; [2024]
    Nyckelord :Electromagnetic power transfer; Inductive power transfer; Short distance WPT;

    Sammanfattning : In the era of Internet of things (IoT), sensor-equipped devices exchange data over networks. In battery powered IoT devices, the lifespan of the devices is often much longer than the battery life, leading to multiple costly and environmentally hazardous battery replacements during the operational life of the devices.

    Sammanfattning : The EU has proposed an ambitious goal to achieve widespread E-mobility in both the electrical and commercial sectors. To accomplish this, a substantial number of DC fast-charging stations must be built. LÄS MER

  4. 3. ANALYZING THE IMPACT OF PHOTOVOLTAIC AND BATTERIE SYSTEMS ON THE LIFE OF A DISTRIBUTION TRANSFORMER

    Master-uppsats, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Mohamed Mohamed Ali; [2021]
    Nyckelord :Distribution Transformer; PV Penetration; BESS; Self-Consumption; Peak Shaving; HSP; ONAN; Thermal Model; RPF; Paper Insulation; Oil Immersed Transformers.;

    Sammanfattning : This degree project presents a study case in Eskilstuna-Sweden, regarding the effect of the photovoltaic (PV) systems with battery energy storage system (BESS) on a power distribution transformer, and how they could change the transformer lifespan. For that, an extensive literature review has been conducted, and two MATLAB models were used to simulate the system. LÄS MER

  5. 4. Allowing more solar power connected to the grid, using thermal and ageing models of distribution transformers.

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Amena Khatun; [2021]
    Nyckelord :electric power distribution; solar power; renewable-electricity production; hosting capacity; distribution transformers; dynamic thermal rating; component ageing; component overloading.;

    Sammanfattning : Increasing amounts of solar power connected to the low-voltage network will adversely affect the performance of the network. The two impacts that will most often set the limit are overvoltage with the customers and overloading the distribution transformer. LÄS MER

  7. 5. Evaluation of Energy Losses in a Wind Farm

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Gabriel Claesson; [2021]
    Nyckelord :;

    Sammanfattning : In recent years, the power production from wind power and other renewable energy sources has increased significantly. Arguably, this is due to the greenhouse effect and the economic benefit of generating power from the wind. Wind power has the potential to replace other non-renewable power sources. LÄS MER
